[0027] Refer to Figure 4 and Figure 5 As shown, the fan frame mentioned in this technical solution includes an outer frame 24 and a motor mounting seat 22 disposed inside the outer frame 24. The motor mounting seat 22 is connected to the outer frame 24 by three connecting ribs 23. The motor mounting seat 22 and the outer frame 24 are separated by three connecting ribs 23 into three air inlet channels 25. When the fan frame is cast, the surplus material is mainly located outside the bottom surface of the motor mounting seat 22, that is, the surplus material is located in the air inlet channel 25

[0028] Refer to Figures 1 to 3 As shown, the punching device for the remaining material of the fan frame includes: a punching platform 1, which is arranged above the ground, and the punching platform 1 provides a supporting platform for punching the remaining material; a positioning block 2, which is arranged at the upper end of the punching platform 1, and the positioning block 2 is used to fix the fan frame. Refer to Figure 1 and Figure 4 As shown, the positioning block 2 is cylindrical, and a positioning groove is recessed in the central part of the positioning block 2. The positioning groove corresponds to the rotor seat in the motor mounting seat 22 of the fan frame. The fan frame is placed upside down at the positioning block 2 to fix the fan frame; a blanking hole 3, a plurality of blanking holes 3 are uniformly arranged on the surface of the punching platform 1 along the outer periphery of the positioning block 2. Since the remaining material of the fan frame needs to be cut off, the setting of the blanking hole 3 can make the remaining material fall through the blanking hole 3 after being cut off, and the situation that the remaining material is scattered on the punching platform 1 will not occur; a collecting box 4, which is arranged below the punching platform 1. The collecting box 4 is mainly used for collecting the remaining material, so as to facilitate remelting the remaining material subsequently; a punching plate mechanism 5, which is arranged above the punching platform 1. The bottom of the punching plate mechanism 5 has a punching surface 6, and a plurality of punching members 7 protrude from the bottom of the punching surface 6. The plurality of punching members 7 enclose a containing space 8. The punching plate mechanism 5 moves downward so that the punching members 7 cut off the remaining material on the fan frame; in this technical solution, the fan frame is placed on the punching platform 1 and limited and fixed by the positioning block 2, and then the punching plate mechanism 5 moves downward so that the punching members 7 move downward. The number of the punching members 7 is three, and their shapes are adapted to the air inlet passage 25 of the fan frame. When the punching members 7 move downward, they enter the air inlet passage 25 to cut off the remaining material. The cut-off remaining material falls into the collecting box 4 through the blanking hole 3 for unified collection. The containing space 8 formed by enclosing the three punching members 7 is mainly used to adapt to the motor mounting seat 22 and the connecting ribs 23 of the fan frame. The containing space 8 can provide a safety control for the motor mounting seat 22 and the connecting ribs 23, and prevent the punching plate mechanism 5 from damaging the fan frame.

[0029] Refer to Figure 1 As shown, a support frame 9 is arranged at the lower end of the punching platform 1. The support frame 9 is used to support the punching platform 1, and the support frame 9 makes the punching platform 1 located above the ground; an inclined guide plate 10 is arranged inside the support frame 9. The collecting box 4 is located below the guide plate 10, and the guide plate 10 is located below the punching platform 1. The inclined guide plate 10 has its top located below the blanking hole 3. The remaining material falling through the blanking hole 3 moves to the collecting box 4 through the guide plate 10. It should be noted that the guide plate 10 is of a U-shaped structure.

[0030] Refer to Figures 1 to 3Above the punching platform 1 shown, a mounting plate 12 is fixed by four guide posts 11. At the upper end of the mounting plate 12, a servo cylinder 13 is fixed. At the lower end of the mounting plate 12, a guide plate 14 is provided. The guide plate 14 is slidably sleeved outside the four guide posts 11. The punching plate mechanism 5 is fixed to the lower end of the guide plate 14. The output end of the servo cylinder 13 passes through the mounting plate 12 and is connected to the guide plate 14. The servo cylinder 13 is used to provide a power source for the guide plate 14. The four guide posts 11 are arranged in a rectangular structure. The bottom of the guide post 11 is fixed to the punching platform 1. The top of the guide post 11 has a threaded section, and the diameter of this threaded section is smaller than the diameter of the main body part of the guide post 11. This threaded section passes through the mounting plate 12 and the mounting plate 12 is fastened to the guide post 11 by a nut. The guide plate 14 can move up and down relative to the guide post 11. The guide plate 14 is a rectangular plate-like structure. At the four corners of the guide plate 14, connecting ears protrude. A guide hole is penetrated at the connecting ear, and a bushing is fixed in the guide hole. The inner diameter of the bushing is the same as the outer diameter of the guide post 11. The servo cylinder 13 can control the guide plate 14 to move up and down. The servo cylinder 13 is a prior art, and those skilled in the art can select it according to actual needs.

[0031] Refer to Figures 1 to 3 As shown, the punching plate mechanism 5 includes a fixing plate 15. The fixing plate 15 is fixed to the lower end of the guide plate 14.

At the four corners of the bottom of the punching plate 16, sinking grooves are provided. A mounting hole is penetrated inside the sinking groove. The depth of the sinking groove is greater than the thickness of the bottom of the guiding member 17. The rod part of the guiding member 17 passes through the mounting hole and is connected to the fixing plate 15. The servo cylinder 13 applies a downward force to the guide plate 14 so that the punching plate 16 moves downward. The surplus material of the fan frame is cut off by the punching member 7 at the punching plate 16. Since a spring 18 is provided between the fixing plate 15 and the punching plate 16, a buffering force is provided when the punching plate 16 cuts the surplus material.
